WATER-HEATER.

SPECIFICATION forming part of Letters Patent No. 666,389, dated January 22, 1901.

Application filed October 8,1900. Serial No. 32,337. (No model.)

. will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings, and to the letters of reference marked thereon, which form a part of this speciiication.

My invention relates to improvements in water-heaters, my object being to provide a structure which is simple, cheap, and durable by which water can be rapidly heated and whose parts can be readily cleaned, it having been found that periodical cleaning iS necessary with heaters used with hard water.

To these ends, and also to improve generally upon devices of the nature indicated, myinvention consists in the various matters hereinafter described and claimed,

In the accompanying drawings, Figure 1 is a front elevation of the present heater, the door being open. Fig. 2 is a side elevation thereof, a portion of this view being in central vertical section. Fig. 3 is a rear elevation thereof. Fig. 4 is a horizontal sectional view on the line 4 4.- of Fig. l, some of the grate-bars being removed; and Fig. 5 is a vertical sectional view of the grate and ashpan supporting member on the line 5 5 of Fig. l.

Referring now more particularly to the drawings, A A represent, respectively, the front and rear water-receiving sections, the front section A being an arched member having the inner wall ct, the outer wall a', the front wall a2, connecting said inner and outer walls, and the bottom wall a3, connecting the bottoms of the said inner, outer, and front walls. The said front wall a2 extends only across the space between the inner and outer walls, whereby an arched opening is left into the section, said opening being adapted to be closed by a suitable door B, hinged to the front wall upon one of the legs of the arch. The rear section A is generally similar to said front section, having the inner, outer,

and bottom walls; but in this section the outer wall, to a height just below7 the smoke-hole as, extends rearwardly beyond the inner wall, and said outer wall and the upper longer portions of the inner wall are connected at their rear by a rear wall a4, while the shorter portions of said inner wall are connected at their rear byan inner rear wall a5, the said walls (t4 and ctextending entirely across the spaces between said outer and inner walls,respectively. A horizontal top wall alo connects the top of the wall o5 with the wall a4. A water-space is thus produced in the legs and across the arch of each of said sections and also at the rear of the lower portion of said rear section. In the rear wall a4 are provided suitable openings ai and o7 for the attachment of the inlet and outlet pipes, respectively, and in said wall is also provided a smoke-hole as for the reception of a suitable pipe o9. The said sections A and A are detachably held together by means of rods C, extending longitudinally through the water space and projecting through the front and rear walls, where they are provided with suitable nuts c. It will at once be apparent that the said sections can be cheaply and easily made and assembled and can be quickly and conveniently separated and that when separated the waterspaces can be readily cleaned. Manifestly should a larger heater be desired an additional section or sections having inner, outer, and bottom walls can be inserted between the front and rear sections above described.

The water-receiving sections rest upon'a base member E, which has downwardly and upwardly inclined side walls e, front Walle', and rear wall c2, saidside walls having at 4their tops outwardly-extending flanges e3,

upon the inner edges of which are upwardlyprojecting ribs e4, while the said rear wall extends upwardly to about the height of these ribs. The bottoms of the legs of the waterreceiving sections rest upon the flanges e3, the upwardly-extending portion of the rear wall of the base member abutting against the inner face of the inner rear wall a5 of the section A and the ribs e4 abutting against the inner faces of the inner walls ct. The sections A A are thus properly positioned upon the base member and may be fastened thereto in any convenient manner.

IOO

Transverse bars e5, attached to the inner faces of the front and rear walls of the base memberor formed integrally therewith, serve to support grate-bars D, and the front wall e' being of less depth than the side and rear walls said side walls extend inwardly at their bottoms to produce supports or flanges e6 for flanges fupon the upper edges of the sides of an ash-pan F. A space sufficient to accommodate these anges f is left between the said supports e6 and the lower edge of the front wall e', while the rear wall e2 forms a stop for the ash-pan. The said front wall is provided with suitable draft-apertures e7, controlled by a slide or gate es, mounted upon said front wall.

Suitable legs I-I are bolted to the side walls e and have their upper and inner faces abutting against the flanges e3 and the said walls, thus aording a firm support.

The present device is simple, convenient, and durable and rapidly heats the water.

Having thus described my invention, what I claim as new, and desire to secure by Letters Patent, is-

l. In a water-heater, an arched water-receiving member comprising a front wall, inner and outer walls connected thereto and having a water-space between them, said inner wall having rear portions shorter than said outer wall, a rear wall connecting and extending across the space inclosed by said outer wall and also connecting the longer portion of said inner wall, an inner rear wall connecting and extending across the space inf-losed by the shorter portions of the inner wall, and a wall connecting the end of' said inner rear wall with said rear wall, whereby a water-space is produced between said rear walls; substantially as described.

2. In a water-heater, an arched water-receiving member comprising a front wall, inner and outer walls connected thereto and having a water-space between them, said front wall extending only across the space between said inner and outer walls, and a door adapted to close the opening bounded by the said inner wall, whereby the said arched member and said door produce a fire-box; substantally as described.

3. In a water-heater, an arched front section comprising a front wall, inner and outer walls connected thereto and having a waterspace between them, said front wall extending only across the space between said inner and outer walls, a door hinged upon one of the legs of said front wall and adapted to close the opening bounded by said inner wall, a rear arched section having inner and outer walls adapted to register with the inner and outer walls of said front section, said inner wall of lthe said rear section having rear portions shorter than said outer wall, a rear Wall connecting and extending across the space bounded by said outer wall and also connecting the longer portion of said inner wall, an inner rear wall connecting and extending across the space bounded by the short-er portions of said inner wall, a top wall connecting the top of said inner rear wall with said rear wall, a smoke-opening in said rear wall between the inner wall and the said top wall, water inlet and outlet openings in said rear wall and leading to the water-spaces adjoining the same, and means for detachably holding said sections together; substantially as described.

4. In a device of the nature indicated, an upper member having side and rear walls adapted to Form walls of a fire-box, in combination with a base member having side walls, and a rear wall, flanges extending laterally from said side Walls, and ribs upon said flanges, said rear Wall extending above the said side walls, whereby said rear wall and said ribs lie against the inner faces of the rear and side walls of the said upper member; substantially as described.
